Lovejoy 68514476950 Flexible Bellows Clamp 1/2 Inch

Product Description

The LOVEJOY 68514476950 is a clamp-style flexible bellows coupling designed for shaft-to-shaft connections in motion control and power transmission applications. The aluminum hub paired with a stainless steel bellows element provides torsional stiffness while accommodating minor angular, parallel, and axial misalignment. With an overall length of 1.614 inches, an outside diameter of 1.28 inches, and a rated torque of 40 inch-pounds, this compact coupling suits precision drive systems where reliable torque transfer and corrosion resistance are required. It is part of the LOVEJOY BWC series and is sold in individual units.

This coupling is used in light-to-medium duty drive trains found in industrial automation, servo motor assemblies, pump drives, and similar rotary power transmission setups. The clamp-style hub design allows secure shaft retention without set screws, reducing the risk of shaft marring. The 1/2 inch minimum bore diameter makes it appropriate for small-diameter motor and gearbox shafts common in compact drive packages. Installation is handled by mechanical technicians and motion control specialists working on precision equipment.

Key Features

• Clamp-style hub provides secure shaft grip without damaging shaft surface
• Stainless steel bellows element accommodates misalignment while maintaining torsional rigidity
• Aluminum hub keeps assembly weight low for high-speed or inertia-sensitive applications
• Rated torque of 40 inch-pounds suitable for light-to-medium duty servo and motor applications
• Compact profile at 1.614 inches overall length fits space-constrained drive systems
• Part of the LOVEJOY BWC series for consistent replacement and sourcing

Compatibility

Designed as an OEM-style replacement or direct-fit coupling for 1/2 inch bore shaft applications within the LOVEJOY BWC series (Size Code BWC41). Consult LOVEJOY BWC series documentation to confirm shaft diameter and torque requirements before installation.

Installation Notes

De-energize and lock out all connected drive equipment before installing or removing this coupling per applicable LOTO procedures. Ensure both mating shafts are clean, free of burrs, and within the specified bore diameter before seating the clamp hubs. Torque the clamp fasteners evenly and verify shaft alignment after installation to protect the bellows element from premature fatigue. This type of coupling is typically installed by mechanical or electromechanical technicians familiar with motion control drive systems.
